We get a lot of questions about the differences between the silver brazing fluxes we make and where each one should be used, so we've prepared a short guide that provides the answers.
A fluxing agent (or a controlled atmosphere as found in furnace brazing) is required for all brazing and soldering applications. The purpose of the flux is to remove oxides from the base material and to prevent oxidation during the heating process, thus promoting the free flow of the brazing filler metal.
Gas welding and braze welding both require skill, patience and an oxy-fuel torch. There are several differences, however, between the two applications that require different techniques and materials.
Gas regulators are designed to reduce pressure to a usable volume for a specific application. What happens when gas flows into a single stage regulator?
Both are solid wire oxyfuel welding rods, but each has its own distinct characteristics.
If you look at a list of brazing filler metals you’ll note many compositions and a variety of melting temperatures. The melting characteristics of brazing filler metal are an important aspect in filler metal selection. Here's a brief outline of how alloys melt and the way to use this information to make the best selection.
Titanium can be cut with an oxy-fuel torch as long as you take certain precautions to protect yourself and your work area.
It is required in the U.S. by OSHA and the Compressed Gas Association (CGA) that cylinder valves be designed differently to prevent interchangeability with gas systems and equipment. This is one of the most important safety practices in the gas industry.
Many different types of metals can be brazed. Copper, and copper based materials like brass and bronze, are typically brazed with copper phosphorus silver alloys also known as American Welding Society (AWS) BCuP filler metals.
A flashback is an uncontrolled flame that recesses back into your oxy-fuel gas equipment, upstream of the location where the gas is designed to mix. In order to have a flashback you must have oxygen and fuel mixed together.
